Malmo's experiment involved turning off the lights during the delay phase, not the training or recall phases. Despite the darkness, the monkeys were still able to identify the correct well with high accuracy (about 85% of trials), demonstrating that they had formed a memory of the correct location that did not rely on visual cues at the moment of recall.
